Github Issue - https://github.com/tootsuite/mastodon/issues/4791
In short, Mastodon's implementation of ActivityPub has resulted in protocol-breaking changes to Mastodon instances that break reply chains federating to GNUsocial, postActiv, and Pleroma. Rather than fix the issue, Gargron has taken to mocking those who would have the oStatus compatibility maintained as Luddites and trolls instead of fixing the problem and cooperating with other developers and instance admins within the federation.
He has also confirmed in several posts that his intent was to Embrace, Extend, and Extinguish the oStatus protocol from the start, and intends to either force GNUsocial instances to conform to his federation protocol by pushing ActivityPub.
